IMPROVEMENT IN BROOCH-PINS.

Specification forming part of Letters Patent No. 204,047, dated May 21,1878; application filed January 30, 1878.

To all whom it may concern:

Be it known that I, JOEL JENKINS, of the city of Brooklyn, county ofKings, and State of New York, haveinvented a new and useful Improvementin the Manufacture of Brooch,- Pins; and that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,making part of this specification.

This invention is in the nature of an improvement in the manufacture ofbrooch-pins; and the invention consists in, as a new article ofmanufacture, a bearing for brooch-pins, constructed with a tubularportion and a flat portion integral and in continuous strips, and thehead of the pin formed solid and in continuous strips, with its severalparts integral, and with holes drilled therein for the reception of thepin, and a rivet for uniting it to the bearing, the bearings andpin-heads being complete when out into sections without the use ofsolder; and the invention also consists in constructing the bearing withits tongue flat on two sides and serrated on its edges.

In the accompanying sheet of drawings, Figure 1 represents a plan or topview of a blank from which is formed a strip for the bearings'jofcelluloidjand similar ornaments; Fig. 2, a cross-section of same; Fig.3, a plan or top view of strip for bearings drawn from sheet of metal bydies; Fig. 4, a plan or top view of a bearing cut from such strip; Fig.5, a cross-section of same; Fig. 6, a view of tube to form strip forbearings which are to be soldered to metal backs; Fig. 7, across-section of same; Fig.8, a plan or top view of strip for bearingsdrawn from tube; Fig. 9, a plan or top view of bearing out from suchstrip; Fig. 10, a cross-section of same; Fig. 11, a plan or top view ofstrip of wire drawn by dies forEthe heads of the pins; Fig. 12, a crosssection of same; Fig. 13, a side view of strip for heads with holes forpins; Fig. 14., a crosssection of same; Fig. 15, a plan or top view ofstrip forheads, with pins inserted; Fig.16, a plan or top view of head,with pin therein cut from such strip; Fig. 17, a side view of same;Figs. 18 and 19, a side view and section of same, with rivet inserted tokey the pin;

Fig. 20, bearing cut from tube-strip, with head and pintherein andsoldered to metal back; Fig. 21, a side view of same; Fig. 22,alongitudinal ,section of same; Fig. 23, a bearing from sheet-metalstrip, with head and pin thrust into celluloid or similar ornament; andFig. 24, a cross-section of same, showing serrations on edge of tongueof bearing.

Similar letters of referen ce indicate like parts in-the severalfigures.

A represents a continuous strip of bearings for the pin. This is formedby takinga piece of thin sheet metal, a, folding it over against itself,and drawing it through a series of holes a bearing for the pin, thetubular portion b of the bearing constituting the eyes for the insertionof the rivet to hold the pin in place, and the other portion, 0, of thebearing forming a tongue, whereby the bearing may be secured tocelluloid or other articles of jewelry of like character bysimplyheating the tongue and forcing it into the substance of theornament to which it is to be attached. To insure the tongue remainingfixed to such ornament, the edges of the tongue '0 are serrated, asshown at l in Fig. 24.

If desired, the bearing may be made without the tongue 6, but still in acontinuous strip, by forming the bearing of a tube, 0, and by drawingsuch tube through a series of dies until it assumes the form shown inFig. 8. In this case the tubular portion f is reduced to form the eyefor the rivet, as in the other case; but, instead of a tongue, the metalis simply flattened out somewhat, as at g, Fig. 9, to make a bettersurface for soldering the bearing to a metal back, as in Fig. 20, andfor this kind of attachment the bearing formed from tubing is designed.The tubular hearing, however, has seats formed in it, and it is cut insections E in precisely the same manner as the bearings formed fromsheet metal, as before described.

Now, to form the head d of the pin, or that portion of it which is to bereceived within the seat 0 of the bearing, a wire, r, of brass or othersuitable metal and of suitable gage, is likewise drawn to a continuouslength through dies until it assumes the shape shown in Fig. 11. Thisstrip for the heads at of the pins is solid, and it is then cut to therequired length to be received within the seat of the bearing; butbefore it is cut for this purpose a series of holes, h, are drilledthrough it, as shown in Figs. 13 and 14. Into these holes is insertedthe unsharpened end of the pin D, and the head is then drilled in thedirection of its length, as shown at s in Figs. 18 and 19. The strip ofheads being then cut, as before stated, to the size necessary to fitthem within the seat a of the bearing, arivet, i,ispassed through theeye I) of the bearing and through the hole which has been drilledlengthwise into the head, uniting the head to the bearing by ahinge-joint, and since the hole which is drilled in the head for thereception of this rivet necessarily passes through one side of the pinD, which is inserted in the head, a recess, j, is formed in the pin bythis means, so that when the rivett' is in place it not only forms thepivot that enables the head to turn within the bearing and uniting thetwo together, but it also, bypassing into the recess j, just described,

in that portion of the pin which enters the head, keys the pin to thehead itself, as shown in Figs. 18 and 19.

By this process of constructing brooch-pins it will be seen that nosolder is employed or is necessary. The pins are not only madeexceptionally strong, but with great facility and economy. The tongue 6of the bearing being flat, it is prevented from turning in the substanceinto which it is inserted, and, as before stated, the serrations Z onthe edge of the tongue prevent it from being withdrawn, so that the flatsides of the tongue and its serrated edges combined make a close unionbe tween the bearing and the ornament it is fastened to.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. As a new article of manufacture, bearing B for brooch-pins, with thetubular portion b and the flat portion 0 thereof integral and incontinuous strips, and the head cl of the pin formed solid in continuousstrips, with its several parts integral, and with holes h and s''drilled therein,the bearings and pin-heads being complete when out intosections without the use of solder, substantially as described.

2. The tongue of a brooch-pin bearing flat on two sides and serrated onits edges, substantially as and for the purpose set forth.
